Tulsi Prajapati, a friend of Sheikh and witness in the encounter case, was shot dead in an "encounter" by Special Operation Group (SOG) of Banaskantha Police in 2006 at a time when CID (Crime), which was probing the Sohrabuddin case, was trying to reach out to him for recording statement.

The Prajapati case is being probed by the State CID (Crime).
CBI, which took over the investigation following a Supreme Court direction in January, has also sought the papers of Prajapati case, which according to the agency officials, is linked to Sohrabuddin.
